Unit 13 We are trying to save the earth. 第三课时 能力提升螂综合拓展 一、阅读理解 Hundreds of years ago,life was much harder than it is today.People didn't have modern machines.There was no modern medicine,either. Life today has brought new problems.One of the biggest is pollution.Water pollution has made our rivers and lakes dirty.It kills our fish and pollutes our drinking water.Noise pollution makes us talk louder and become angry more easily.Air pollution is the most serious kind of pollution.It's bad to all living things in the world.Cars,planes and factories all pollute our air every day.Sometimes the polluted air is so thick that it is like a quilt over a city.This kind of quilt is called smog(烟雾). Many countries are making rules to fight pollution.Factories must now clean their water before it is thrown away,they mustn't blow dirty smoke into the air. We need to do many other things.We can put waste things in the dustbin and not throw it on the ground.We can go to work by bus or with our friends in the same car.If there are fewer people driving,there will be less pollution. Rules are not enough.Every person must help to fight pollution. ()1.What is the biggest problem in today's life according to the text? A.Food. B.Transportation. C.Noise. D.Pollution. ()2.The most serious kind of pollution is A.noise pollution B.air pollution C.water pollution D.smog ()3.What can we do to help protect the environment? A.Throw away litter everywhere. B.Take the bus to work. C.Drive our own cars often. D.Ask factories to pour waste water into the rivers. ()4.From the passage we know that. A.a few years ago,there was no smog at all B.today people don't have to talk to each other in a loud voice C.we can drink water from the polluted rivers and lakes D.people are making rules in order to fight pollution 035 页语山九年级下册人教版》 二、完形填空 Edgar McGregor is a20-year-old climate activist(气候话动家).He spent589 days picking up litter from Eaton Canyon.Eaton Canyon is a part of the Angeles National Forest in southern California. Edgar promised to picking up litter left by visitors and posted his 1 on the net.He has more than 17.000 followers! Edgar started this 2 when he learned that Los Angeles would be hosting the Olympic Games in2028.He thought the litter would be a“national embarrassment(尴尬)”for the United States.He decided to start with 3 Eaton Canyon first since he lives closest to it.It includes many trails (and waterfalls as well as homeless tents. Thanks to his work,the park is now free of 4.Edgar said recently that there was no longer 5 at the park.However,his work is not done.He plans to go back to the park often to keep its clean6.

(show)that 85%of the old backpacks ended up in rubbish.But as we know,most backpacks are 036 Unit 13 We are trying to save the earth. produced from different 3.

This invention isn't just for fun-it shows how humans copy nature to solve problems.That is a science called bionics. Over millions of years,animals and plants have developed smart 》signal信号 ways to survive.For example,kingfishers are experts at moving fast between air and water with very little noise.Through their study, sensor scientists discovered that the birds'long beaks (enabled this 传感器 ability.Then they used the knowledge to change the front of the high- motor马达 speed train.This change cut down noise level,increased speed by 10%and greatly saved energy. This combination (of biology and engineering is the key to success in bionics.And it has set the stage for the rise of other new technologies. Driven by robotics and Al,bionics has grown rapidly.The AI-powered bionic fish "Jinlin" can be used for environmental protection and deep sea exploration.In medicine,bionic arms can work similarly to real arms.Sensors allow the user to "feel"touch and pressure.Motors help the bionic arms make movements,like human muscles ()With AI,the bionic arms are able to "learn"new tasks and become smarter over time.These inventions are examples to show how bionics bridges biology and new technologies to solve humans'problems. Although so much progress has been made,bionics faces challenges.Nature's designs are hard to copy perfectly.As for bionic arms,one key area of development is Brain-Computer Interface(脑机接口).More work on direct communication between the brain and bionic arms is 037 页语山九年级下册人教版》 required to control movements as naturally as real arms.Researchers are also working on creating new materials and structures which can sense and repair themselves. While there's still a long way to go,the future of bionics is full of possibilities.Stay hungry. Stay foolish.Maybe you'll be the next one to change the world! ()1.Why does the writer mention "Jinlin"at the beginning of the passage? A.To suggest some new ideas. B.To lead into the topic of bionics. C.To explain the habits of fish. D.To show the importance of bionics. ()2.What can we learn from Paragraph 3? A.Robotics and AI have developed fast because of bionics. B.The bionic fish "Jinlin"is used for medical purposes. C.Motors allow the bionic arms to make movements. D.Sensors help bionic arms learn new tasks over time. ()3.According to Paragraph 4,how would scientists make bionic arms more like real ones? DBy connecting motors with smart phones. 2By developing new materials and structures. 3By improving Brain-Computer Interface. 4By changing the shape and look of bionic arms. A.①② B.①④ C.②③ D.③④ ()4.Which of the following shows the use of bionics? A.Drawing a picture of birds by watching real birds. B.Building a house with natural materials like wood. C.Designing a camera by copying some insects'eyes.
